ROOFING-TILE.

Specification of Letters Patent.

Patented Sept. 27, 1921.

Application filed December 14, 1920. Serial No. 430,593.

To all whom it may concern:

Be it known that I, ISRAEL GREENBERG, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Roofing-Tiles, of which the following isa specification.

This invention relates to improvements in roofing tiles, and has for itsobject to provide a tile that is especially adapted for roofing andsimilar purposes, and which is simple and durable in construction and soformed that when placed in position the overlapping ends will interlockand form a tight joint as well as to prevent the ends.

of the tiles from being raised by the wind or otherwise. A furtherobject of my invention is to prevent breakage of the tile in shipment orin handling same.

The invention consists of the novel construction and arrangement of theparts hereinafter more fully set forth in the following specificationand pointed out in detail in the appended claim.

In the accompanying drawing,

Figure 1 is a top plan view of my improved tile.

Fig. 2 is aninverted plan view of same.

Fig. 3 is a section on the line 4 1 of Fig. 1.

Fig. 4 is an end view of Fig. 2.

Referring to the accompanying drawing, forming part of thisspecification, and in which like reference numerals designate like partsthroughout the several views thereof, 1 designates the body of the tilewhich is provided with two grooves 2 in its upper surface and a centralgroove 3 in its under surface. The upper surface of the tile is alsoprovided with grooves 4 at one side to receive the projection 5 on theunderside of the overlapping edge of the adjoining tile.

One end of the tile is provided with an integral piece 6 extending fromone side of the tile to a point where the adjoining tile overlaps thusforming a continuous piece across the edge of the tiles when laidtogether thereby preventing the rain or water from being blown up underthe tile when laid in position. On the underside of the tile are twolugs 7 which fit under the strips of the roof (not shown) and two lugs 9which fit into the grooves 2 just back of the cross piece 6 of the tilebelow. The under surface of. the tile is also provided with two parallelprojections 10 near the center thereof and on opposite sides ofthegroove 3. A wire.

11 is embedded in the projections 10 and extends across the groove 3 andrests upon the upper surface of the webs 12 which are integral with thetile and have their lower surfaces flushed with the lower surface ofsaid tile. The said wire 11 strengthens the tile in the middle where thegreatest strain generally occurs and will reduce the breakage of sameeither lengthwise or crosswise.

Having thus described my invention what I claim is A roofing tile havingits sides adapted to overlap and two grooves in its upper surface and acentral groove in its lower surface thereof, two lugs on the lowersurface of the tile adapted to fit in the grooves on the upper surfaceof the adjoining tile,.two webs extending across the central groove 3and having their lower surfaces flushed with a lower surface of thetile, two integral parallel projections on the lower surface of the tileon opposite sides of said central groove, and a wire embedded in saidprojections and extending across and resting against the lower surfaceof said webs.

In testimony whereof I aifix my signature.

ISRAEL GREENBERG.
